I got these blades from a different source, but since I was browsing here I wanted to comment on them. I have used several blades, Derby, Family Dollar (Personna), Dollar General (Dorco), WalMart Wilkinsons, and Indian Gillette Green. While I have not a problem with any of them, these Crystals are far and away superior. All the other blades made me regret trying a fourth shave. I Have now finished my seventh shave with the one Crystal I have used and I still don't intend to change it out. It just keeps shaving smoothly with no irritation. A couple of tips from a newb DE shavor: DO NOT get obsessed with getting too close a shave. You will beat your face up and this will cause you problems the next day. If you aren't getting your 5 O'clock shadow until 10PM, you are shaving too close. You should have a shadow on your drive home from work. If you don't beat your face up, you can give yourself an additional shave in the evening if you are going out and don't want a shadow. The other tip is one I read about and works great. Your beard has oils on it from your skin that waterproof it. Wash your face with enthusiasm using your hands and bath soap before you hydrate it (preferably in the shower). This allows the water to actually penetrate your beard and soften it. When I get in the shower, I wash my face first and then run it under the shower a few times as I take the rest of my shower. Then I hit the pause button on the shower head and shave in the shower. The trickel from the shower head is enough to rinse the razor and I can hear the blade working with the water reduced to a trickel. Anyway, these blades are cheap and fantastic. Buy the 100 pack.
